The War of 1812 12

The nation was divided over the war, with the South and West supporting it while New York and New England opposed it because it affected trade. The U. S. military was weak, with fewer than 7,000 regular soldiers. The conflict began with an unsuccessful invasion of Canada, leading to the British taking Detroit, but the U. S. Navy had some successes. In 1813, General William Henry Harrison aimed to reclaim Detroit, and with news of Commodore Oliver Hazard Perry's victory on Lake Erie, Harrison succeeded in pushing British forces back.

In 1814, Commodore Thomas Macdonough won a naval battle, forcing a British retreat. However, the British attacked Washington, D. C. , burning it down. Peace talks led to the Treaty of Ghent in December 1814, which finished hostilities and restored territories. Despite the war ending, fighting continued into 1815 in New Orleans, where General Andrew Jackson achieved a significant victory.

In New England, Federalists opposed the war, claiming it harmed the economy, and proposed amendments to protect their interests. The war's end, marked by the victory at New Orleans, left the Federalists with a reputation of disloyalty.
